COLREGS-based Path Planning for Ships at Sea Using Velocity Obstacles
IEEE Access, 2021 Recent studies have made significant development in path planning for ships. However some studies blindly obey rules of COLREGS (International Regulations for Preventing Collisions at Sea) or only adopt turning to starboard ignoring actual practice, like,

Finite-time ship formation control based on extended state observer
Zhongguo Jianchuan Yanjiu, 2023 ObjectiveIn order to solve the problems of most current ship formation control algorithms such as their long control cycle and poor timeliness, this paper proposes a finite-time control strategy based on an extended state observer (ESO).MethodsFirst, a ...

Optimal Navigation Functions for Nonlinear Stochastic Systems
, 2014 This paper presents a new methodology to craft navigation functions for nonlinear systems with stochastic uncertainty. The method relies on the transformation of the Hamilton-Jacobi-Bellman (HJB) equation into a linear partial differential equation. This
